Abstract

The invention provides a method for preparing all-solid waste high-strength glass ceramics by using coke slag as the main material. The method uses 50-95% of coke slag, 0-45% of magnesium slag, 0-15% of white mud, 2-10% of titanium slag and 3-10% of sodium hypophosphite waste slag as raw materials. , pouring molding and one-time crystallization method to prepare high-strength glass ceramics. The preparation process of the method is simple, and the solid waste utilization rate is 100%, which can effectively solve the environmental pollution problem caused by the coke slag, magnesium slag, white mud, titanium slag and sodium hypophosphite waste slag solid waste. The flexural strength of the glass ceramics prepared by the present invention can reach more than 300MPa, the product has good wear resistance and corrosion resistance, soft color, good texture and high added value, and can be used as building decoration materials and industrial wear and corrosion resistant materials And the production of handicrafts, the market prospect is broad.

Description

technical field [0001] The invention belongs to the technical field of new materials and environmental protection, and in particular relates to a method for preparing all-solid-waste high-strength glass ceramics with coke slag as the main material. Background technique [0002] With the development of China's economy, it is increasingly dependent on oil, known as "industrial blood". According to statistics, my country's consumption of refined oil will reach 2.6×10 by 2020 8 tons / year. Crude oil needs to be refined to become refined oil. Most of the crude oil is heavy oil, which needs to be decomposed into light oil through sulfur catalytic cracking (FCC) technology, and the most important thing in catalytic cracking technology is catalytic cracking catalyst. Due to the increased demand for refined oil, the accelerated production of catalytic cracking catalysts has been stimulated, which has also greatly increased the amount of solid waste emitted during the production of pe...
